  • Nuclear Fuel Cycle Department of Energy

    Milling produces a uranium oxide concentrate which is shipped from the mill. In the milling process uranium is extracted from the crushed and ground-up ore by leaching in which either a strong acid or a strong alkaline solution is used to dissolve the uranium oxide. The uranium oxide is then precipitated and removed from the solution.

  • NRC Uranium Conversion
